Police say a Braintree teenager who had been smoking marijuana crashed into a police cruiser while trying to video record a crash scene on Sunday night.

Police said the cruiser was parked outside a North Braintree Square 7-Eleven store -- where a driver had crashed into a storefront window earlier in the evening -- when William T. Sawyer, Jr., 18, rear-ended the cruiser while trying to record the scene with his cell phone camera. An officer was in the cruiser at the time, but police said he was not seriously uninjured.

Police said Sawyer’s car smelled strongly of a marijuana after the crash. Sawyer was due to be arraigned Monday on several charges, including driving under the influence of drugs, driving to endanger and obstructing an emergency vehicle.

Police said the driver who crashed into the store, a 68-year-old Weymouth woman, was not charged. No one was inside the store was injured.
